How does recommendation work? There used to be a site called mov3y which was also on HN a while ago, and I loved it. this gives me similar vibes. that site did recommendations by finding users who also rated movies you have rated about the same score and i found that to work really well.

I haven't heard of mov3y, but it sounds very similar. On peepthis a 'compatibility score' is routinely generated and updated between you and other users, as determined by the similarity of your ratings. Your 'predicted ratings' for titles are also routinely generated and updated, as determined by the existing ratings of your most compatible users. So different users will have very different recommendations based on what users with similar taste like, rather than having monolithic "best of" recommendations that are only based on average rating and popularity.

I was heavily inspired by www.criticker.com which is the best site for film recommendations that I've found and I've been using it for over a decade. However it's feeling pretty dated at this point and I also wanted to apply the same concept to books, music, etc. which is why I decided to create my own platform.
